hi can any body tell me why hardcore free for all is not in ghost when thousands of players want to play it but and have gone back to mw3 for that reason !! come on infinity ward put it back in please !!!

Because it's only thousands of players that want to play it and not tens of thousands. HC fans have been shafted in this game and even after the addition of HC Dom to the playlist, we still are. Play core FFA, put a black sticker over the minimap and pretend it's HC, after all the amount of time it takes to kill is very similar.
